Cardiac hydatid over the interventricular septum is extremely rare. Echinococcus infests humans as an accidental host. Echocardiography usually clinches the diagnosis of cardiac hydatid. However, multimodality imaging including cardiac magnetic resonance (CMR) imaging, computed tomography (CT), and positron emission tomography (PET) helps in supporting the diagnosis and surgical planning.
We present a 29-year-old male who presented with dyspnea and was found to have cardiac hydatid on the interventricular septum on echocardiography. CT and CMR clinched the diagnosis. CT pulmonary angiography showed extensive pulmonary thromboembolization and cavitary consolidation in lungs. PET showed no active uptake in cardiac hydatid. Post-surgical enucleation of the cyst his hypotension worsened and succumbed.
Cardiac hydatid has poor prognosis. Multimodality imaging helps in confirming the diagnosis and surgical planning.
位于室间隔的心脏包虫极为罕见。棘球绦虫将人类作为偶然宿主进行感染。超声心动图通常可确诊心脏包虫。然而，包括心脏磁共振（CMR）成像、计算机断层扫描（CT）和正电子发射断层扫描（PET）在内的多模态成像有助于支持诊断和手术规划。
我们报告一名29岁男性，因呼吸困难就诊，超声心动图检查发现其室间隔有心脏包虫。CT和CMR确诊了病情。CT肺动脉造影显示肺部广泛的肺血栓栓塞和空洞性实变。PET显示心脏包虫无活性摄取。囊肿手术后摘除，他的低血压恶化并最终死亡。
心脏包虫预后不良。多模态成像有助于确诊和手术规划。
